The typical networkNetwork with minimal variability in the color thickness and spacing of the lines; symmetrically distributed is regularly meshed and composed of lines that are relatively uniform in width and homogenous in colorColor (American English) or colour (Commonwealth English) is the characteristic of human visual perception described through color categories, with names such as red, yellow, purple, or blue.; the lines often become gradually thinner and fainter in pigmentation at the lesion’s periphery:

An example of a typical pigment networkNetwork with minimal variability in the color, thickness, and spacing of the lines; symmetrically distributed delicate network light brown, thin network lines clinically and dermoscopically:

On histopathologyThis glossary term has not yet been described., the lines of the typical network correspond to pigment in the rete ridgesEpidermal extensions that project into the underlying dermis, that are relatively uniform in width and equidistant from each other.

The typical network usually corresponds to the junctional component of a nevusThis glossary term has not yet been described.. However, reticulation can also be seen in darkly pigmented normal skin and in heavily pigmented rete ridges as encountered in dermatofibromas, ink spot lentigo or accessory nipples [1].

This traditionally consists of a magnifier (typically x10), a non-polarised light source, a transparent plate and a liquid medium between the instrument and the skin, and allows inspection of skin lesions unobstructed by skin surface reflections. Modern dermatoscopes dispense with the use of liquid medium and instead use polarised light to cancel out skin surface reflections.algorithmIn mathematics and computer science, an algorithm (Listeni/ˈælɡərɪðəm/ AL-gə-ri-dhəm) is a self-contained sequence of actions to be performed.
